HANDLE-BAR FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 602,600, dated April 19, 1898. Application filed February 19, 1895. SeriaINo. 539,003. (No model.)

To whom it may concern.

Be it known that I, GEORGE S. GREEN, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalama zoo and State of Michigan, have invented certain new and useful Improvements in Hand le- Bars for Bicycles, of which the following is a specification.

My invention relates to improvements in bicycles, and more particularly to improvements in bicycle handle-bars and their connection to the handle-bar post.

The object of my invention is to provide a simple and compact adjustable joint between the handle-bars and the handle-bar post which will permit of substantially parallel adjustment of the handles at the end of the handle-bar up and down.

Another object is to provide in a bicycle a quick and convenient means of adjusting the handle-bars so that they can beheld securely.

I accomplish these objects of myinvention by the devices shown in the accompanying drawings, in which Figure 1 is a perspective View of a pair of handle-bars embodying my invention connected to the handle-bar post, the same being detached from the bicycle. Fig. 2 is an enlarged detail sectional view on line 2 2 of Figs. 1 and 3'through the central part of my improved joint. Fig. 3 is an enlarged detail view showing the relation of one handle-bar to the handle-bar post and the corrugations at the top of the handle-bar post. Fig. 4 is a sectional view on line 4 4c of Fig. 5 corresponding to a view on line 2 2 of Fig. 1, showing a modified construction. Fig. 5 is a detail view similar to the detail view shown in Fig. 3, showing the same modification as in Fig. 4. Fig. 6 is an enlarged sectional detail view of a very quick means of adjusting the handles in connection with the bolt D.

Similar letters of reference refer to similar parts throughout the several views.

Referring to-the lettered parts of the drawings, O represents the handle-bar post.

A represents the head of the machine,which receives the handle-bar post.

B B represent the handle-bars to each side.

B 13 represent the flattened joint portions at the ends of the handle-bars.

0 represents the flattened corrugated part of the handle-bar posts C, it being corrugated on both sides, and D represents the bolt for securing the same together.

In the construction of my device I first fiatten the top end of the handle-bar post together and form thereon corrugations, as will be readily seen in Figs. 1,2, and 3. I flatten the end of each handle-bar and form corresponding corrugations upon them and fit them to the front and to the rear of the corrugations on the flattened portion of the handlebar post. Then I pass a bolt D through all three and place a thumb-nut D upon it to clamp the same all securely together. In forming the joint at each end I extend the handle-bar around the disk portion B B as far as possible in order to secure as strong a connection between the handle-bar B and part B as possible.

To adjust the handle-bars, the thumb-nut D is loosened, the handle-bars moved up and down to the desired position, and then the thumb-nut tightened again. This construction answers all requirements.

A modification showing a convenient and 1 strong construction is shown in Figs. 4 and 5. In this instance instead of the corrugations pins a are formed on the central part 0,

adapted to fit into apertures a in the disk portion B of the handle-bars to engage the handle-bars. The pins are placed accurately the same distance apart all the way around the central part, so that they engage readily in the holes. The adjustment is accomplished the same as before, except it requires a little more care, but makes a neater and smoother joint when completed.

Fig. 6 shows a very quick and satisfactory means of adjusting the handle-bars when the corrugations or pins are used. At one end of the plate D, on the pivot T, is pivoted a little eccentric cam F, which is operated by a little hand-lever. On the bolt D, inside between the ends B B of the handle-bar, a spring E is placed to spread the same and throw them apart. The handle to the cam is thrown up to release the handles, the handlebars swung to position, and the handle to the cam thrown down. This makes a very quick adjustment and for greatest convenience is preferred to the thumb-nut D, although the thumb-nut D for ordinary use will be found preferable, as it is less expensive and less likely to get out of order.

I am aware that handle-bars for bicycles have been made adjustable heretofore so that the outer ends of the handle-bars can be adjusted in a substantially parallel position, but each handle-bar was taken into a separate joint, and from all that I am aware the joints used for the purpose were unsatisfactory, allowing the handle-bars to slip in heavy Work.

It is clear from my description that my improved handle bars and post can be considerably varied without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a bicycle, the combination of the handle-bars, B, B, the inner ends of which are flattened into disk-like portions, B, B, having corrugations opposed to each otherythe handle-barpost, O, flattened into the disk, 0, corresponding in size to the disks, B, having corrugations upon both sides corresponding to the corrugations on the disk portions, B, B; a bolt, D, exten'ling through said disks to clamp the same together; and an eccentric cam, F, pivoted on said bolt operated by a suitable lever for adjusting the tension on the bolt to permit of quick adjustment of the handle-bars, for the purpose specified.

2. In a bicycle, the combination of the handle-bars, B, B, the inner ends of which are flattened into disk-like portions B B, corrugated on their faces; the handle-bar post, C, the upper end of which is flattened into the disk 0, and suitably corrugated to engage the handle-bars,corresponding in size to the disks, B; an adjusting-bolt passing through said disks to clamp the same together to permit of an adjustment of the handle-bars, for the purpose speoified.

In Witness whereof I have hereunto set my hand and seal in the presence of two Witnesses.
